Watch: New Batman v Superman Teaser

Set in what looks like a military bunker, the teaser opens on a chained-up Batman (Ben Affleck) looking around at his bleak surroundings with terror.

When Superman (Henry Cavill) drops down, obedient soldiers bow down before him. He strides toward the Dark Knight and rips off his rubber mask, revealing his true identity -- and that's all we get. But things don't seem to be going well--for anyone.

Batman v Superman: Dawn of Justice opens in theaters March 25, 2016.
